launch rpm

I was told yrs. ago if you have a good converter you should not need to bring it up agianst it that's the pont in getting one in the frist place.its to shock the chassie like a clutch.and if it wasn't you need more converter.were ever your converter locks up should be around 1000 rpms.above were your cam starts making power.how do you check your stull speed well drive along at around 30mph.and in high gear.(asoming you have a manual shift valve body) let up on the gas pedle then stand on it watching tha tic and were ever you see the tack stop and start pulling the car that were your converter is locking up....I have know a lot of big time racers in my time that didn't know that.sorry if I steped on any toes I did not read all the coments on this.but Im sure there are a lot of good racers on here that has already ansered your Qustion. all of this is assuming you have a car that is working and just because the coverter says its a 35 or5500 stull dosent mean it is unless its a costum vert for your car and that a nuther ball game.be safe and think before you stab it....Artie
